| Summary: | 碩士 === 國立交通大學 === 電控工程研究所 === 104 === User experience (UX), especially usability, becomes more and more important when designing a website. Before launching a website, UX designers conduct ‘Usability Testing’ to
estimate the usability of the website. Due to the limitation of budget and time, ‘Usability Testing’ hardly covers the variety of subjects. After launching the website, some UX designers
adopt Web Analytic tools to collect user behaviour, but most Web Analytic tools only provide
statistics rather than goal-oriented data analysis. To solve the above challenges, we propose a
User eXperience Analysis Model (UXAM) to provide goal-oriented data analysis by considering the variety of subjects. UXAM consists of two phases: Feature Extraction and Feature
Analysis. In the Feature Extraction phase, UXAM converts the user logs of a website into
sessions, exploits the features of each session, and classifies the sessions into different session
groups according to their features. During the Feature Analysis phase, UXAM estimates the
usability of each session groups and gives suggestions to improve the usability of the website.
We conduct experiments to evaluate the usability of the personnel website of a university in
Taiwan. The experiments show that UXAM can figure out the relationship among links of the
navigation menu. With the suggestions given by UXAM, an administrator can place a web link
at a proper place and merge some pages or links to eliminate the complication of a web page.
The thesis is concluded with a new web page redesigned with the suggestions given by UXAM.
